Economic Incentives in the Digital Art Market

Abstract

Non-fungible tokens (NFTs) are assets on a blockchain that represent ownership of digital art and are traded on NFT marketplaces. The NFT market on the Ethereum blockchain was monopolistic until the end of 2022, when a new marketplace entered and captured a significant market share. This paper collects transactions from these marketplaces to study the effects of increased competition on the incumbent marketplace, artists, and investors. While competition had positive effects by reducing transaction costs, increasing trading volume and attracting new users, it decreased the profits of artists, discouraged them from creating new artwork, and thereby reduced the supply of new assets. I also study user migration, multi-homing behavior, and market segmentation, and compares the results with the predictions from theories of platform economics.
